Styling a frill abaya for different occasions can transform its look from casual to formal effortlessly. For a casual day out, pair the frill abaya with simple, comfortable shoes like flats or sneakers, and minimal accessories, letting the frills add a playful touch to your outfit. Opt for lighter fabrics and neutral colors for a relaxed vibe. For a semi-formal event, choose a frill abaya in a richer fabric like satin or silk, and complement it with heeled sandals or ankle boots. Add a statement belt to accentuate your waist and some elegant jewelry to elevate the look.
